So, I just encountered this issue today and I know the item is fairly new, but it's very annoying right now. I have been using the bundle for storage and I have noticed that when I close out of my inventory and re-open it again, if I had a bundle inside of another bundle, the bundle inside would get deleted and everything else in it. I have lost allot of valuable materials from this and it's a little frustrating. I was able to replicate this multiple times, and the same exact thing happened. In the photo I included it also glitched out the bundle making it seem like it was full, yet it had nothing in it. I don't know what is going on.
